In a stark reflection of the crisis engulfing New Caledonia’s nickel industry, Société Le Nickel (SLN) has announced it will “mothball” its Thio mining center, the birthplace of global nickel production. Once celebrated as the heart of New Caledonia’s mining sector, Thio has been brought to a standstill by political unrest and infrastructure damage stemming from riots earlier this year. The decision marks the first time in its 140-year history that SLN has ceased operations at Thio, which employed 230 workers directly and supported 120 subcontracting jobs.
The closure is emblematic of deeper challenges plaguing New Caledonia’s mining industry, including competition from Indonesia, now the world’s largest nickel producer. With lower production costs and aggressive expansion, Indonesian producers have eroded the market share of traditional players like SLN. Compounding the situation are the region’s soaring energy costs, which have crippled local metallurgical operations. Earlier this year, Koniambo Nickel SAS shut its northern facility, displacing 1,700 workers, leaving the territory’s economy reeling.
SLN’s inability to maintain operations is also linked to the destruction of critical infrastructure, including conveyor systems, mining equipment, and employee housing, during the protests. Guillaume Kurek, CEO of SLN, described the shutdown as inevitable given “absolute and lasting barriers” to accessing the mines. Thio’s mayor, Jean-Patrick Toura, lamented the loss, noting the mine had sustained the local economy for over a century.
TThe downturn in New Caledonia’s nickel sector carries significant repercussions for global markets. As a critical component in electric vehicle batteries and stainless steel production, nickel plays an indispensable role in industries central to the global energy transition. Any prolonged supply disruptions from New Caledonia, historically a key player in the market, could exacerbate tightening inventories and drive up prices, further straining manufacturers dependent on stable supply chains. Without swift policy reforms or substantial new investments to revive operations and competitiveness, New Caledonia risks losing its longstanding position as a pivotal contributor to the global nickel industry.
